Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
What's new in version 1.2:
• Import almost anything: Word (.doc/.docx), classic PowerPoint (.ppt), Excel, OpenDocument, RTF, EPUB, and CSV files now convert to decks entirely on your Mac — no upload, no account, powered by a bundled offline converter.
• Now available in 12 languages — Lectern AI is fully localized into Arabic, Simplified & Traditional Chinese, Dutch, French, German, Italian, Japanese, Korean, Brazilian Portuguese, Russian, and Spanish.
• Sharper diagram understanding (Pro): visual slide analysis now locates each chart or diagram on the slide and reads a full-resolution close-up, so labels and values make it into your talk track.
• Vision sidecar (Pro): if your selected AI model can't see images, Lectern automatically borrows a vision-capable model from another provider you've configured — fastest writer and sharpest eyes, in the same run.
• Scanned-PDF OCR (optional): image-only PDFs can be recovered via Firecrawl Parse with your own key — always behind an explicit disclosure before anything is uploaded.
• Faster visual analysis: image-heavy slides are now read in parallel, and a live status banner shows exactly which AI engine is reading and which is writing.
• Current-generation AI models across every provider, with honest benchmark-backed defaults.
• Stronger privacy & security: hardened how local and custom AI providers connect (endpoint validation and redirect protection), and your API keys are no longer kept in plain text at rest.
• Reliability and polish fixes throughout.
